緊急時運転手順の知的CAIシステムの開発

抄録

The intelligent computer-assisted instruction (CAI) system has been developed for plant operators to study emergency procedure guidelines by themselves. The system has two types of tutoring courses : teaching text knowledge by using a question and answer and teaching actual procedures and process behavior by using a simulator. The system instructs operators according to their understanding levels evaluated by the student model, which is common to both courses. The main characteristics of the system are as follows : The student model is combined with a hierarchical function model which is considered as the plant operator's mental model, and The understanding level of each node (element) is evaluated by personal history conditions calculated from both the tutoring record of the node and the understanding level of the connecting nodes. The student model and tutoring strategy function were evaluated using seven students of different understanding levels. It was confirmed that the developed system could successfully determine their understanding levels and recommend proper courses according to them.
